Hi Dave,
Welcome to WAB
Please don't refrain from posting, because as you say, there are always people asking for help over an invasion of something or another, and to hear a professional's point of view would be interesting. After all, you must have seen and heard ot all before
There may well be debates over the best way to tackle such problems, but it is interesting to hear all povs
Oh, and enjoy the rest of the forums!
D.
